High voltage power cables can generate local high temperatures in the casing during operation or overload, and MPP pipes can still ensure sufficient ring stiffness at high temperatures to protect high-voltage cables.
MPP pipes have strong compressive and impact resistance, and their ring stiffness is much higher than that of HDPE pipes. Even if the pipes are buried deep, MPP pipes can withstand significant soil pressure without significant deformation. MPP pipes have good impact resistance in low and high temperature environments.
In non excavation projects such as horizontal directional cobalt injection with strong adaptability to the environment, pipes and welding points need to withstand large tensile and bending forces. MPP pipes have superior tensile and bending resistance and can be suitable for harsh non excavation application conditions.
MPP pipes with flexibility and bendability have considerable axial flexibility and bendability.
